Numerous investigations have demonstrated the role of thrombus formation in the pathogenesis of coronary heart disease (CHD). A tendency to thrombosis may also be indicated by elevated levels of coagulation factor VII clotting activity (FVIIc). Significant associations of FVIIc with increased coronary risk, however, have been found only in the Northwick Park Heart Study. Here we present the results of the 8-year follow-up of FVIIc measurements in 2780 healthy men of the Prospective Cardiovascular Munster study. In the study population (age at entry, 49.3 +/- 6.1 years, mean +/- SD), 130 CHD events occurred during follow-up. FVIIc was significantly higher in subjects with coronary events than in those without (112.4 +/- 20.1% vs 108.7 +/- 21.4%, P = .023). Compared with individuals without coronary events, FVIIc was not significantly higher in men with nonfatal events (111.7 +/- 20.4%; P = .196, n = 93), but there was a tendency toward higher FVIIc activity in subjects with fatal events (114.6 +/- 19.5%; P = .076, n = 37). In the multiple logistic regression analysis, we did not find FVIIc to be an independent risk factor for CHD, and the significance of FVIIc disappeared after total cholesterol, LDL-cholesterol, and triglycerides were taken into account. The increase in the number of CHD events through higher levels of FVIIc was more pronounced in the presence of additional cardiovascular risk factorssmoking; myocardial infarction events in family; angina pectoris; high levels of fibrinogen, total cholesterol, LDL cholesterol, and triglycerides; and a low level of HDL cholesterol. We conclude that FVIIc is a risk factor for CHD, especially in the presence of additional risk factors, and must be taken into account when assessing cardiovascular risk in men.
